If I were to passively split with a "Y" my guitar's cable sending it to two different amps would I be compromising the signal received at each amp? I mean does splitting it from the guitar to run 2 amps weaken it by half or is there enough signal when split that the amps would receive enough input signal?

Good question, but an ABY pedal doesn't cost much and you can get one that will deal with ground issues. I use one from Radial that I bought over ten years ago, back when they were fifty bucks or so.

I was going to feed my guitar into a stereo delay and take the left to feed one amp and the the right for the other. In a way this buffers the signal giving a strong feed to both amps. But my question about a passive split has me wondering if there would be any difference in signals due to the split.

Chances are a passive splitter will work fine because the signal is high impedance. The first gain stage of a guitar amp is designed to deal with that.
The best way to do it (less opportunity for noise) is a stereo out off a pedal like you're doing.

Radial or stereo delay.
I have both.. currently using a TC Flashback on my rig.
Like I need two amps at home.
Anyway...

You aren't going to be happy with a Y splitter.
Any stereo pedal will do the job, even if it's never turned on.
Go Radial or whatnot if you're gigging and have to deal with changing ground stuff, but if you're just at home - try a stereo pedal, if no issue, don't worry about a ground-selectable fancy splitter.

I mean does splitting it from the guitar to run 2 amps weaken it by half or is there enough signal when split that the amps would receive enough input signal? Amp inputs are very high impedance, eg 1M, hence the current level is miniscule. So it’s just a voltage signal, no power per se is drawn. So it’s a very different scenario to say connecting an extension speaker cab to an amp’s output. Hence a guitar could easily feed 2 or 3 amp channel inputs with hardly any signal loss. The bigger problem would be that the additional cabling will tend to increase the capacitance loading on the guitar. As it mounts up, tone may be affected a little. And as mentioned previously, connecting an unbalanced signal to 2 or more items of mains earthed equipment can cause earth loop hum. The use of signal transformers in splitter boxes allows such loops to be broken without compromising electrical safety. |
